s Claims. (Cl. 12s-8) constructing binders for large sheets in substan tial numbers, particularly binders of the kind known as public record binders for use in keeping county records and the like.

The invention provides a binder having a rigid sheet metal back member formed at opposite sides with spaced parallel binder bars tofsupport locking members for inter-engagement with locking members on sheet transfer bars for locking a sheet body in the back member. This back member at the same time provides a support for the covers and the back cover structure.

The invention comprehends a binder for large heavy sheets having a rigid sheet metal back construction formed at opposite sides to provide binder bars having the sheet body attached and bound directly thereto through the mounting of the transfer bars thereon, at the same time providing a mounting for the back and cover members arranged in such a manner, that the completed binder can be produced at a substantially low cost.

The invention comprehends novel structural features in the back Construction of the binder directed to the formation of rigid binder bars at opposite sides of the sheet metal plate, the securing of transfer bars thereto, the mounting of hinges for the covers, and the Provision of locking tongues on the back plate engaged in slots in the back member for attaching the back plate in assembled relation on the binder.

In the drawing:

Figure 1 is an elevation looking at the inside of the binder from which the sheet body has been removed showing portions of the inner lining for the back structure broken away and re.- moved to illustrate the back construction, portions being shown in cross section, the lower cover being shown in closed position and the upper cover being shown in open position with the free end portion broken away.

Figure 2 is a cross section taken on line 2-2 of Fig. 1 with portions of the bottom transfer bar broken away to illustrate the structure of the slidable latch for retaining the transfer bar attached to the binder bar.

Figure 3 is a cross section taken on line 3-.3 of Fig. l.

Figure 4 is a viewV of one end portion of the back member showing the outer face thereof from which the back plate has been omitted in order to illustrate details of construction and how the hingestrips are mounted!l thereon.

The main back member of the binder is formed of a sheet metal plate curved into partially cylinfdrical form and has anges on the side edges extended laterally in` spaced parallel relation to form binder bars 2 terminating in inturned lips 3. The partially cylindrical portion of back member I is arranged in relation to binder bars 2 to curve outwardly away from the plane of the bars. The integral binder bars 2 and lips 3 at opposite sides of back member I are formed near opposite ends with recesses 4.

A locking bar 5. is slidably mounted on the under face of each binder bar 2 along the inside face of lip 3. Each bar 5 is slidably retained in engagement with the under face of its binder bar by means of pairs of retaining and guide pins 6 extending through pairs of slots I in each end portion of the bar on oppositevsides of each recess 4, as shown in Fig. 2. One end of each bar 5 is formed with a lateral extension to provide an actuating handle 8, so the bar may be manually gripped and moved into operative or inoperative positions, in a manner that will subsequently appear. Each bar 5 is formed in the portions overlying slotsv 4 with cut-out sections 9 for forming retaining pintles I0 on the edge of the bar adjacent the inside face of' lip 3. Pintles I8 extend across slots 4 in the binder bars and lip 3 in the locking position of locking bar 5 and are moved into position to leave the entrance to said slots 4 open when the bar is moved into the release position.

The sheet body for the binder is indicated in dot and dash lines at II in Fig. 3. A pair of transfer bars I2 are provided for engagement with opposite sides of the sheet body and have binding posts I3 projecting at spaced intervals from said bars to extend through openings in the binding edge of the sheet body. The binding posts on one transfer bar are arranged in offset relation to the binding posts on the other transfer` bar in. order to overlap in the sheet body. The ends of the posts extend. entirely through the sheet body into approximate contact with the transfer bar on the opposite side of the sheet body. The arrangement of the binding posts on the transfer bars is such that the transfer bars may be applied to either side of the sheet body interchangeably.

Each transfer bar is provided with securing loops I4 mounted on the face opposite posts I3. A pair of loops are provided on each transfer bar at opposite end portions thereof positioned -toengage in slots 4 in 4binder. bars Zand lipsv` 3.

When loops.. L4 lare positioned.r in slots 4., as

shown in Figs. 1 and 3, they may be aligned with pintles I so that by the sliding movement of locking bars from the releasing to the locking position, pintles I0 may be engaged within loops I4 to retain the transfer bars and the sheet body engaged on the posts thereof in bound relation with said binder bars and back member.

Covers I5 are suitably mounted on thinge plates I6, a separatel hinge plate II-being provided for Y*each cover, having one edge of 'each hinge plate provided with hinge portions complementary to hinge portions on supporting hinge plates II- Supporting hinge plates I'I are suitably secured to the outerback face `of back The hinge to lie adjacent to the juncture between the side edges of back member I and binder bars 2 thereon, as shown in Fig, 3.

The binder is provided with a back structure having a partially cylindrical back plate 2D of the same shape as back member I. A suitable binding material in sheet form such as imitation leather, buckram, canvas or the like indicated at 2| is applied as a cover over the outside face of back plate and has the edges turned around the edge portions of plate 20 and secured to the inside face, as clearly shown in Fig. 3. The ends of back plate 20 are formed with lateral projections 22 as shown in Fig. 2 and binding material 2| is extended around these flanges over the inside adjacent faces of the lateral extensions and Iadjacent portions of the back plate. The back plate and binder material may be provided with the usual transversely extending ribs 23 by forming offsets at spaced intervals, `:as shown in Fig. 2.

:through slots 25 in the central portion of back member I and bent laterally over the inner face of back member I as shown in Fig. l,- some of `the ears being turned in one direction and other ears being turned in the opposite direction, preferably in alternate relation, for firmly attaching back plate 20 to back member I. In the attached relation of back plate 20 with its binding cover 2I thereon the laterally extending portions 22 at the ends will engage over the ends of back member I, in the 'manner shown in Figs. 1 and 2, to cover the structural parts of the binder and give it a finished appearance. The inside face of back member I is provided with a suitable covering material indicated at 25 applied after the back plate 2i) is in assembled rel-ation thereon, for covering the turned over ends of tongues 24. 'I'his completes the finish on the binder to enhance its appearance.

The sheet body is readily applied and removed from the binder by manually moving locking bars 5 by engaging handles 8 and moving the bars so as to disengage pintles I0 from loops I4. The transfer bars hold the sheet body together in separated relation from the binder back and cover structure as a unit in a manner wellknown in the art. The sheet body may be replaced in the binder by placing the binding edges of the sheet body carrying the transfer binder.

between binder bars 2. Loops I4 are engaged in slots 4, Upon subsequent sliding movement of locking bars 5 from release to locking position by manual engagement of handles 8, pintles I0 Will be slidably moved through loops I4 for rmly attaching the transfer bars to the cover and back structure to retain the sheet body in the binder.

In adding and removing one or more sheets fromthe binder, or in transferring sheets from one position to another therein, it is not necessary to entirely remove the sheet body from the One of the locking bars 5 may be operated to release the transfer bar from the binder bar at one side of back member I whereupon the released side of back member I may be moved away from the binder bar so that it `may be removed 'from the sheet body with a group of sheets on top of the sheet to be removed or replaced, or at the point Where a new sheet is to be inserted. After this operation is completed the removed binder bar may then be replaced while the other binder bar is still held in attached relation to back member I. Upon replacement of the detached binder bar with the sheets carried by the posts thereof onto the sheet body to assemble the sheet body, the back member I may be moved relative to the transfer bars so that loops I4 on the detached bar may be moved into slots 4 of its correspond- .ing binder bar 2 Iand locking bar 5 again operated to move pintles IIJ into the loops for securing the transfer bar to its binder bar.

This construction of back member I to provide a pair of rigid binder bars on opposite sides thereof provides a very serviceable binder structure for large-size sheets of the type used for public record binders that will stand rough usage with no damage to the binder. This construction of the back member with integral binder bars also provides a simple construction that is convenient for mounting the hinged members for the covers thereon, as well as for the construction and attachment of a back cover unit to finish the binder. The construction above described also Vprovides a loose leaf binder that can be produced in a very economical manner due to the fact that relatively few parts with a simple assembly structure are required to produce a complete binder.
